his. invention relateslto brushes. such. as are used in barber; shopsand; beauty parlors and, am g other: objects, aims-to provide animproved handle'having provision to. secure a bundle of fihcrslorbristles. in; thehandle'socket and improved meanswhereby thefiberspmaybe quickly removecland replaced; so: that amnew or clean briishmaybe.used; on: eachcustomer.

Other aims and advantages of the invention willeappear.- in. thefollowing description, when considered in connectionwith 'theaccompanying drawing, wherein:

v. -brush handle having provision to eject the bristles and to permit anew bunch of hair, fiber or bristles to be inserted so that a sanitarybrush in the same handle can be used on different customers.

Referring particularly to the drawing, the

'brush handle isshown as being made in two sections or parts which maybe of any suitable material and comprises a brush holding or lower part10 and a screw carrying on upper part 11 rotat- -ably mounted on thebrush holding part or section. Referring to Fig. the brush holding partis shown as having a flared bristle socket or opening 12 in the lowerend to receive a bundle of fibers or bristles 13 suitably tied togetheror bent upon themselves to form a loop 14 at the upper end, as shown inFig. 2.

The screw carrying part 1101? the handle preferably has a cylindricalprojection 15 inserted in an axial, cylindrical opening 16 in the upperend j of the part 10 and is secured for relative rotation with respectto said part by means of pins or screws 17 having projections whichextend into an annular groove or channel 18.

The upper section 11 is hollow and preferably has multiple screw-threads19 in the form of helicoidal surfaces generated by angles of equal sideswhose vertices'leanupon helicallines ofconstant pitch. Av screwmember-20 m the form of a cylindrical block having 1 screw-threadsmating with the threads 19 is mounted inthe upper part and: carries a'non-circulanon prismatic plunger rod or ban 21 which extends through anon-circular axialopening 22in the-lower-part and this plungerv carriesa: suitable hook 23 whichmayhave: eithera rounded orpointed end toengage thebristles craloop on a bundle offibers as the casezmaybe. ln lig. 2a wireonrubberloopor ring 24-; isarranged: on the bentportion ofthefibers and: isconnected: to thehook 23. Thear rangement issuchthat theupper part llfl of the handlemay be turnedltoeject the=bristles orfibersby means of the plunger andto pulla new-bundle of fibers into thesocket.

In Fig. 2, there is shown'brush-expelling-means in the-form. of -a1 coilspring 25 within a-cylindrical recess: 26- around: the lowerhookedj endof the plunger-and adapted} to be compressed'by' thebundleofifibersor-br-istles so that, when the plunger is moved downwardlyto ejectv thefiber-s, the. spring. will assist in expelling them from the socket. It;is: contemplated, however, that theplun'ger may be retracted or'pulledinwardly sufliciently far to break the loop 24 so that the spring willeject the loose bristles. This may be done when the bristles are to bedestroyed.

The upper and lower sections of the handle are preferably knurled orroughened, as indicated in Fig. 1, to provide convenient grippingsurfaces and enable the user to turn the sections relative to eachother. The multiple screw-threads, when such threads are used, enablethe bristles to be ejected and replaced by turning the sections only afew turns. The bristles are preferably treated to soften the endportions which rub the face and are impregnated with soap or cosmeticsso that they are ready for instant use.

For barber shop use, especially when cheap bristles are employed, it isdesirable to provide means to destroy the bristles or render themuseless after they have been used on one customer. This may beaccomplished in various ways. For example, the bill of the hook may beso shaped that, when it is removed from they loop of the brush it willscuff or displace the fibers. However, in Fig. 4 there is shown means torender the bristles useless. In this example, a knife blade 27 issecured in the handle section 10 and projects into the socket 12 belowthe spring 25. The bundle of bristles 13 is tied below the loop portion14, in which the plunger hook 23 engages, by a string or band 28. Thisband is cut by the knife as the bundle of bristles is pulled into thesocket. Thus, the fibers are loose and some of them are displaced ortangled when ejected. When using this type of brush, a barber has toinsert a new bundle of bristles every time a used bundle is ejected.

It will be seen that the improved brush handle may be used almostindefinitely and plain, soaped or powdered bristles of different typesor degrees of fineness to suit the needs of the user may be carried instock ready to be secured in the handle socket. One set of handles withdifferently shaped sockets may be provided for different sizes ofbrushes or kinds of bristles. A new or sterilized set of bristles of thesame size may be put in the handle for each customer. It

will be understood that many variations of the bundles of fibers orbristles may be used and that the mode of connecting them to the handle,as well as the shape of the socket, may be widely varied.

Obviously, the present invention is not. restricted to the particularembodiment thereof herein shown and described.

1. .A brush of the character described, .in combination, a handleportion presenting a bristle socket in the lower end; a rotatableportion constituting a part of the handle and removably connected to thebristle carrying portion; screwthreads within said rotatable portion; ascrewthreaded plunger member mounted in said screwthreaded portion ofthe rotatable member and projecting into the socket portion; saidplunger member having a non-circular part slidably and non-rotatablymounted in the socket portion; a

hook member carried by the plunger member; and a bundle of bristlesremovably secured to said hook member whereby'the plunger is utilized toseat the bristles within said socket and toexpel them therefrom so thatanew bundle of bristles may be substituted therefor.

' 2. .A, brush of the character described comprising a two-part handle,one part being rotatably secured to the other; a bristle socket formedin the lower end of one part; a hollow screwthreaded portion in theother part; a non-circular plunger member having an enlarged screwthreadedhead within said hollow screw-threaded portion; said socket parthaving a non-circular opening in which the plunger is slidably mountedand hook means on the lower end of the plunger adapted to be removablyconnected to a bundle of bristles so that the bristles maybe removed andnew ones substituted therefor.

3. A brush of the character described comprising a bristle carryinghandle portion presenting a flared socket at the lower end and having acylindrical recess in the upper end; an upper handle section having acylindrical extension mounted in said cylindrical recess in the bristlecarrying portion; means connecting said portions together so that onemay rotate with respect to the other; multiple screw-threads in thehollow portion of the upper section; a non-circular plunger having ascrew-threaded enlargement mounted in the screw-threaded portion of theupper section, said lower section having a 11011-7 circular opening toreceive. said plunger and prevent it" from rotating; a hook member onthe lower end of the plunger. extending into the bristle socket; abundle of fibers or bristles-removably secured to the hook memberwhereby the fibers or bristlesmay be seated-in the socket or expelledtherefrom; and acoil spring in the upper end of the socket arranged toassist in expellingthe bristles.

.4. A brush comprising a hollow handle having a bristle socket; screwmeans in the handle having a member adapted to secure a 'bun-' dle ofbristles in the socket; and a spring in the socket to expel the bristlestherefrom. i

5-. In a brush of the class described, a handle having a bristle socket;a bundle of bristles composed of reversely bent fibers or hair; abinding band below the upper bent portion; a screwoperated plungerhaving a hook to engage the loop in the bundle of bristles and. pull itinto the socket; and a knife blade in the handle projecting into thesocket arranged to cut the binding band as the bundle of bristles ispulled home so as to render the bundle. useless after it is removed.
